First, is Taylor Swift’s open letter to Apple upbraiding them for not paying royalties to artists for their music during the trial period of its new streaming music service. It caused the weenies at Apple to change their tune.

Second, a high court ruling in the UK which erased an earlier UK decision that made it lawful for users to copy purchased content for personal use. Related is freedom of panorama which permits the photographing of copyrighted buildings and sculptures in public places. Up for vote this summer before the European parliament is legislation that would restrict such rights.

The Swift letter echoes the points she made earlier when she pulled her wares from Spotify:

“In my opinion, the value of an album is, and will continue to be, based on the amount of heart and soul an artist has bled into a body of work, and the financial value that artists (and their labels) place on their music when it goes out into the marketplace.”

One of the more poetic renditions of the labor theory of value I’ve read. Here is another line from the same missive:

“Valuable things should be paid for.”

No. Its the added value of a good or service that commands a premium. Pearsall-Smith got this right when writing of the novelists of his age.

“The diction, the run of phrase of each of them seems quite undistinguishable from that of the others, each of whose pages might have been written by any one of his fellows.”

Thus, the question is whether the heart and soul each artist bleeds into their work serve to differentiate it in a way that matters from others. The effectiveness of music recommender systems suggests not.

Enough of `Swiftian’ logic and lets turn to the UK high court ruling. The Electronic Frontier Foundation complained that it contained more economic theory than common sense. An irritating remark as the level of theory barely exceeded that you would find in an intermediate micro-economics course. It makes me wonder whether the pundits at the EFFs ever went to college.

The ruling is a perfect example of how consistency can become a procrustean bed. The UK government had earlier made the duplication of copyrighted material for personal use legal. It claimed that its reasons for doing were consistent with an EU copyright directive that requires the copyright holder to be compensated for forgone revenues lost to copying. The Judge concluded that the government’s rulings were, in fact, inconsistent with the EU directive and overturned it making copying for personal use illegal.

The law, as Dickens said, is an ass (the quadruped not the posterior). So, lets focus on the economics. The ruling by the way quotes Varian’s 2005 piece in the Journal of Economic Perspectives as well as Boldrin and Levine.

Suppose I sell you a song in a medium which is costly to reproduce and transport. If you want to listen to the song both at home and in your office you must purchase two copies. Now, a sea change. The medium on which the song is transmitted changes. The cost of duplication and transport is now zero. Am I worse off? If I am, then under the EU directive I should be compensated for this loss.

With this sea change, you would buy one fewer copy. However, I, recognizing the sea change gives you the same benefit as buying two copies, can simply raise my price to account for this. The High court ruling called this pricing-in and the case turned upon whether the music seller, me in this example, could perfectly price-in. If not, then under the EU directive I am entitled (bizarre, I know) to compensation for lost profits.

If the sea change allows you to consume music in ways you previously could not (in the bathroom, in your car at night etc.) then it seems obvious that I could anticipate this and price-in. If the sea-change allows you to copy and distribute my music costlessly, then, I may be forced to sell my music at a discount or withhold it (see the Varian paper for intermediate cases). Whether I am harmed or not depends on whether you intend to use the sea change for personal use or to compete with me.

Interestingly, the discussion in the ruling as well as Varian’s paper ignores those who own the devices for transmitting, duplicating, storing and playing the music. Lets use the example in Varian pg. 11. You are willing to pay $20 for home use of a CD and $10 (actually 10 to break ties) for office use. The cost of copying is initially infinity.

The revenue maximizing price is clearly $20 for a CD, unless I could use a 2-part tariff. Now a third party develops a technology for copying CDs that is simple and convenient. Copying is now legal. Under the pricing-in story I should just charge $30 (assuming you have the technology). I’m better off and you are no worse off. However, we have ignored the owner of the copying technology. You, the music consumer have $30 to shell out. I can certainly capture $20 of it but to capture the remaining $10, I need the owner of the copying technology. Any simultaneous split of the $10 is a Nash equilibrium. The point is that the music and the technology that allows one to copy, format shift etc complements the music itself. That $10 is a joint gain to the owner of the song as well as the owner of the copying technology. One might argue that the owner of the copying technology is entitled to the full $10 as it is her innovation that allowed one to capture it. Hence, the copyright holder, me in this example, suffers no loss from the fact you can now copy my music.

Orwell’s review of Penguin books is in the news today courtesy of Amazon vs Hachette. You can read here about that here. I wish, however, to draw your attention to an example that Orwell makes in his review:

It is, of course, a great mistake to imagine that cheap books are good for the book trade. Actually it is just the other way around. If you have, for instance, five shillings to spend and the normal price of a book is half-a-crown, you are quite likely to spend your whole five shillings on two books. But if books are sixpence each you are not going to buy ten of them, because you don’t want as many as ten; your saturation-point will have been reached long before that. Probably you will buy three sixpenny books and spend the rest of your five shillings on seats at the ‘movies’. Hence the cheaper the books become, the less money is spent on books.

Milton Friedman in his textbook Price Theory, as an exercise, asks readers to analyze the passage. He does not explicitly say what he is looking for, but I would guess this: what can you say about the preferences for such a statement to be true. Its a delightful question. A budget line is given and a point that maximizes utility on the budget lie is identified. Now the price of one of the goods falls, and another utility maximizing point is identified. What kind of utility function would exhibit such behavior?
By the way, there are 60 pence to a shilling and a half a crown is six pennies.
